Geometric transformations can be distinguished into two types: active or alibi transformations which change the physical position of a set of points relative to a fixed frame of reference or coordinate system (alibi meaning "being somewhere else at the same time"); and passive or alias transformations which leave points fixed but change the ...
An active Brownian particle (ABP) is a model of self-propelled motion in a dissipative environment. [ 1 ] [ 2 ] [ 3 ] It is a nonequilibrium generalization of a Brownian particle . The self-propulsion results from a force that acts on the particle's center of mass and points in the direction of an intrinsic body axis (the particle orientation ...
There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. This process is in contrast to passive transport , which allows molecules or ions to move down their concentration gradient, from an area of high concentration to an area ...
Illustration of the "reference directions" of the current (), voltage (), and power () variables used in the passive sign convention.If positive current is defined as flowing into the device terminal which is defined to be positive voltage, then positive power (big arrow) given by the equation = represents electric power flowing into the device, and negative power represents power flowing out.
The effectiveness of traditional instruction and passive learning methods have been under debate for some time. [2] The modern origins of progressive education, with active learning as a component, can be traced back to the 18th century works of John Locke and Jean-Jacques Rousseau, both of whom are known as forerunners of ideas that would be developed by 20th century theorists such as John Dewey.
A bare passive clause is similar to a typical passive clause, but without the passive auxiliary verb (so it is a non-finite clause consisting of a subject together with a verb phrase based on a past participle with the passive construction). These can be used in such contexts as newspaper headlines:
